Hi Peng, If the BFD packets are lost, doesn’t the BFD session go DOWN? Are you saying that packet loss is not big enough to make BFD session go DOWN? Thanks Regards Mallik From: <Fan>, Peng <fanpeng@chinamobile.com<mailto:fanpeng@chinamobile.com>> Date: Friday, 28 November 2014 4:20 pm To: "rtg-bfd@ietf.org<mailto:rtg-bfd@ietf.org>" <rtg-bfd@ietf.org<mailto:rtg-bfd@ietf.org>> Subject: RE: BFD stability follow-up from IETF-91 Hi Jeff, all, I have been following this stability extension from the beginning, and as an operator I would like to express that this draft enables the "advanced feature" we desire for BFD to provide additional useful information that helps operators understand network issues. A relevant use case is detecting lossy or "quasi-disconnected" links or member LAG links. An example of such situation we experienced was a loosely connected fiber link resulting in continuous, small amount of packet loss. BFD could get the information of lost BFD frames on such unstable link, and probably report when a target level is reached, say a certain number of frames are lost over a period or among a total number of frames. Best regards, Peng
